no top end power

I have a 97 f150 4x4 with the triton 4.6 L. I have noticed recently that it is lacking a little all through the rpm range but has really dropped off at higher speeds and rpms. It has 105,000 miles on it and the plugs have been changed recently and the air filter is clean. I am beginning to suspect that the catylitic converter is clogged, because it has never been changed. Please share some info if you've had any similar experiences it will be greatly appreciated.

Have you tried cleaning the MAF sensor?
How old is the fuel filter?

i haven't cleaned the MAF sensor, and i'm not exactly sure how old the fuel filter is but i bet it hasn't been changed in a long time. Thanks for the help, i'll try both of these and see if it helps
